The mismatch occurs because the lens metadata within the image differs slightly from the lens metadata within the profile. This can happen because different units of the same lens model can sometimes have different IDs. Fortunately, there is a simple yet effective workaround: You can establish a custom default. Once you've manually picked the correct lens profile, choose "Save New Lens Profile Defaults" from the "Setup" popup menu. In the future, all images taken with this lens should find the correct profile when checking the "Enable Profile Corrections" box.
